Quantitative analysis of carotenoids has been extensively reported using UV-Vis spectrophotometry and chromatography, instrumental techniques that require complex extraction protocols with organic solvents. Fourier transform infrared spectroscopy (FTIR) is a potential alternative for simplifying the food constituents. In this work, application FTIR attenuated total reflectance (ATR) was evaluated determination carotenoid content (TCC) in Cucurbita spp. samples. Sixty-three samples, belonging...

Bee pollen (BP) is a natural product with remarkable nutritional and bioactive composition. Some of the compounds interest are carotenoids provitamin A activity, possessing an excellent antioxidant capacity positive health effects. For that, objective this work was to characterize botanical origin carotenoid profile in two particle sizes Colombian BP by Rapid Resolution Liquid Chromatography (RRLC). The α-tocopherol content were obtained, ANOVA analysis employed explore data. main found...

Interest in bioprocess-based products has increased recent years due to their applications and advantages. Solid-state fermentation, as a part of this technology, been used different industries, including food. Among the produced with type process, bee bread is one most important. Bee pollen valuable raw material because its nutritional characteristics, particular protein (10–52%), lipid (.15–20%), dietary fiber (.3–20%), mineral contents, well bioactive qualities related presence vitamins...

Abstract Vegetable substrates are food matrices with micronutrients, antioxidants, and fiber content a high potential for bioprocesses development. In addition, they have been recognized as essential sources of wide range phytochemicals that, individually or in combination, can act bioactive compounds benefits to health due their antioxidant antimicrobial activity recently status prebiotics the balance human intestinal microbiota. This systematic review explores lactic fermentation plant...

The blackberry (Rubus glaucus Benth) and the bilberry (Vaccinium meridionale Swartz) are natural sources of antioxidants; they known for their preventive role against degenerative diseases. In this study, aromatic profile was evaluated using an electronic nose, including antioxidant properties vitamin C, phenolic anthocyanin contents during three stages ripening. A completely random statistical design followed results presented differences in profile: a higher content (1.59 mg cyn-3-glu g-1...

The complex composition and high acidity of anthocyanin-rich fruit beverages are challenging factors for the viability probiotics sensory properties potential synbiotic beverages. purpose this study e was to determine a set adequate conditions obtain plant-based beverage with containing anthocyanins. A formulated, one four prebiotic fibers selected based on physicochemical changes assessment index activity toward two different probiotic starters. conglomerate (Pediococcus pentosaceus,...

The interest about probiotic bacteria supplementation in fruit beverages has been increased recently order to develop functional without lactose. That is a technological challenge since pH and storage temperature can affect their viability. aim of this study was evaluate the viability three commercial strains (L. paracasei, L. casei rhamnosus) mango beverage stored at 4°C. This research developed stages: assessment acid strain tolerance, selection prebiotic as cellular protectant against...

The tomato is a Solanaceae plant which globally has the second highest production rate, making it one of most important vegetative products in global and consumption. Furthermore, valued for its antioxidant components, notably vitamin C, phenolic components carotenoids such as lycopene β-carotene. present study aimed to evaluate influence three drying temperatures (50, 60 70°C) on physicochemical, microstructural, characteristics tomato. analyzed parameters color using coordinates CIE L* a*...

Se ha incrementado mercado demanda de que permiten al consumidor implementar hábitos alimenticios más saludables esto acompañado con incremento intolerancia lactosa, lo incentivado investigar, estudiar desarrollar una generación productos origen...

Bioactive compounds of natural matrices are interest because their application in the food and pharmaceutical industries. One important source bioactives is propolis, a resinous biomass that bees make from plants surrounding hive. Regarding Colombian studies have mostly been directed towards identifying flavonoids biological activity vitro. There no works on oil extract propolis its chemical composition bioactivity through metabolomic analysis. In this sense, work studied volatile samples...

Lactic acid bacteria (LAB) are considered as a good alternative to reduce the risk of food borne diseases in industry. In addition improvement effects on organoleptic characteristics fermented foods from LAB metabolites, they can inhibit growth microorganisms responsible spoilage. This work is an advance biodiversity exploration natural additives food. Isolation, identification and screening potential antimicrobial activity were aims this work.
